How a wireless router works
A wireless router is a device that is used to create a wireless
network either at home, in the office or in public places such
at hotels, coffee bars and restaurants etc….
A wireless router works in conjunction with a wireless network card
or adaptor which installed on a PC, laptop or other wireless device.
One adaptor is needed per PC. They must both work in the same
frequency range to allow the transmission of data backwards and
forwards between the devices. With several computers connected
wirelessly to the router you have a Local Area Network (LAN). It
will be possible to share files between the PC’s.
Instead of using a wired connection between the devices, they use a
radio frequency. However, most wireless routers also come with
Ethernet ports so a cable connection can still be achieved between
devices if so desired. The amount of Ethernet ports varies and
typically is 4 ports.
As with wireless adapters, many routers can use more than one 802.11 standard. 802.11b routers are slightly less expensive, but because the standard is older, they're slower than 802.11a, 802.11g and 802.11n routers. Most people select the 802.11g option for its speed and reliability.
